Open-backed HFI-2400 headphone
Ultrasone has announced the latest product in its series of HFI headphones, the HFI-2400. The headphone features 40mm gold-plated drivers, while the company's S-Logic technology is claimed to widen the perceived soundstage. MU Metal shielding is designed to help reduce the amount of magnetic radiation by up to 98% compared to standard headphones. The drivers are built with 70 Ohm impedance and produce a frequency range of 10Hz - 25kHz, with a sound pressure level of 94dB.
Users can pre-order the headset from the company's website for $295, with shipment expected sometime later this month or in November. The package includes a removable 3m cable with a 6.3mm gold-plated stereo plug, an Ultrasone demo CD and a velvet carrying bag.
